Do transplanted eyebrow hairs continue to grow like scalp hair — will I need regular trimming?

Yes. Because the transplanted follicles come from your scalp, they retain scalp-like growth characteristics. This means the new eyebrow hairs may grow longer and faster than natural eyebrow hair. Regular trimming—perhaps every couple of weeks—is usually needed to maintain a neat and natural eyebrow shape. Over time, some hairs may slightly adapt to the new location.
